IMPROVEM ENT IN RAI LWAY-FROGS.

Specification forming part of Letters Patent No. 216,268., dated J nne 10, 1879; application filed March 17, 1879.

Figure l is aplan. Fig. 2 is a cross-section a the dotted line in Fig. 1.

The tongue-block c is of one piece and slotted at one end for the tongue I) to enter. It is provided with a key, 8, which passes through tongue b and rests. in a groove across the top of tongue-block 0, with the ends of the key in contact with the inner side of wingrails a a, the under side of the top flanges of which are in contact with the top of key 8. The wingrails are so curved at their ends as to be reversible and interchangeable. The braceblocks 0 c are bolted to ties between wingrails a a and tongue I). The bolts 6 6 hold Wing-rails a a and tongue 12 together in the ordinary manner, except that bolt 6 passes through the unslotted end of tongue-block 0 beyond the end of tongue b.

The advantages of using key 8 instead of the ordinary screw-bolt to hold the wing-rails and tongue firmly in their relative positions, are that it may be of any suitable size and shape to sustain the strain that it may be subjected to without making holes for it through the win g-rails, and thus weakening them. The downward pressure of trains of cars on tongue I) is borne by key 8 and tongue-blockc resting on the bottom flanges of the rails, and as key 8 does not extend through the rails it is not strained or affected by the varying expansion and contraction of the wing-rails and tongue in the heat of summer and cold of winter.

Tongue-block c by being solid has its own strength and rigidity, in addition to bolts 6 e, to sustain the pressure on it.

I claim as my invention In a railway-frog, the solid ton gue-block 0, provided with key 8, extending only to the inner sides of wing-rails a a, in combination with the tongue I) and interchangeable wingrails a a, substantially as described.
